ALFRED YATES, OF TISSINGTON, COUNTY OF DERBY, ENGLAND.

MACHINE FOR DOUBLING YARN.

SPECIFICATION forming part of Letters Patent No. 258,522, dated May 23, 1882.

Application filed February 4, 1882. (N0 model.) Patented in England September 16, 1881, No. 3,996.

To all whom "it may concern:

Be it known that I, ALFRED YATES, of Tissington,in the county of Derby,England, have invented certain newand useful Improvements in Machines for Doubling Yarn, (for which I have obtained Letters Patent in Great Britain, N0. 3,996,dated September 16, 1881,) of which the following is a specification.

This invention relates more particularly to what are known as doubling-machines, and in which the thread or yarn is usually drawn by drawing-rollers from bobbins supported in a creel through the trough, and then delivered from the rollers through guide-eyes, and thence conducted to the spindle and flier. These rollers are expensive in fitting up and heavy to drive. They also form,when thethread breaks, what is known as roller-laps, causing great waste, and necessitating delicate detector mechanism to stop such rollers in case of threads breaking. Besides, the yarn is often soiled by the oil or dirt on the roller-necks, thus greatly deteriorating its quality.

Now, my invention is designed to dispense with the aforesaid drawing-rollers; and itconsists of the mechanisms hereinafter described and claimed for regulating the delivery of the thread or yarn in the creel itself.

In the accompanying drawings, Figure 1 is a front elevation of the upper part of a doubling-frame, showing the improvements constituting my invention, the spindle, bobbin, ring and foot rails, gearing, &c., being omitted, as any approved form of the same may he used. Fig. 2 is a side view of the same; Fig. 3, an enlarged view of the thread-lever; Fig. 4, an enlarged view of a pulley of the thread-lever; Fig. 5, an enlarged side view, and Fig. 6 a front View, of one of the inclined slides, also enlarged.

Similar letters of reference indicate corresponding parts.

B is one of the pulleys or drums, keyed on a light shaft, A, running throughout the frame and supported by suitable brackets, K, at intervals, the number of drums varying with the length of the frame. The drums are preferably coated with a paint or resinous material. The shaft A is provided with a driving-pulley, A, or is otherwise actuated by any suitable means.

0 are the creel-bobbins, which are supported or which rest on the drums; D, the watertroughs, and E the thread-board, as usual.

F are the small pulleys or beads, of glass or other vitreous material, carried by the bent thread wires or levers G, which are pivoted on a rod, L, said rod passing through metal eyes H, driven into the framing, or in other convenient manner.

J is a piece of metal soldered or otherwise fastened to wires or levers G, acting as a counter-weigh t.

The left-hand side of Fig. 2 shows the thread at the moment of breaking and the weighted lever rising out of the water, while the righthand side shows the lever in the water. The thread passes at one side of the center of the drums from the top of the bobbins, and at the other side from the bottom of the bobbins, and

then from the upper tiers of bobbins over the metal rails M, which are supported at intervals by the brackets K, and provided with notches M M, as shown, through which the thread passes to the pulleys F, and from the lower tier of said bobbins directly to said pulle'ys. These rails M act instead of creel-wires, and besides serve as a part of the frame to carry the inclined arms or slides O O.

N is a shelf at the top of the brackets for bobbins which are not in use.

The slides O O are adjusted at an incline toward the drum in order to hold the bobbins by gravity in contact therewith when the machine is in operation, and provided with central ribs, P, which serve as guides for thebobbins, and semicircular depressions Q, in which the skewers P of the bobbins rest when not in use. The horizontal upper ends of the slides are bolted or otherwise secured to the rails M, which latter are usually composed of angleiron. The lower slides, O, are supported at the lower ends on angle-irons li at the lower parts of the brackets, instead of at the upper ends, as the other slides. The shape and an gle of the various slides are necessarily moditied, as shown, in order to bring the bobbins ot' the difierent tiers into the proper relative positions upon the drum. The slides may be cast in brackets; but I prefer the arrangements shown.

The thread, after passing through the hooks on the thread-board, goes to the spindle and bobbin or spindle and flier, as usual. If a thread breaks, the thread-lever G is instantly raised by its weight out of the trough, and returned again into the same after the thread is tied, the lever being then held down by the tension of the thread. The thread is delivered by the action of the revolving drums on the bobbins, while the pull or drag of the spindle produces a regular tension on the threads without the use of drawing-rollers and other like mechanism.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of a cylindrical drum, means for rotating the drum, a series of downwardly inclined arms arranged at different heights around the drum, in near proximity thereto, which are adapted to hold a series of bobbins in contact with the periphery thereof, a suitable supporting-frame for the drum and arms, and means for guiding the thread from the bobbins, substantially as described.

2. The combination of a cylindrical drum, means for rotating the drum, a series of downwardly inclined arms arranged at diii'erent heights around the drum, in near proximity thereto, which are adapted to hold a series of bobbins in contact with the periphery thereof, said arms being provided with longitudinal guide-ribs, a suitable supporting-frame for the drum and arms, and means for guiding the threads from the bobbins, substantially as described.

3. The combination of a cylindrical drum,

means for rotating the drum, a series of downwardly -inclined arms arranged at different heights around the drum, in near proximity thereto, which are adapted to hold a series of bobbins in contact with the periphery thereof, said arms being provided with longitudinal guide-ribs and with notches or depressions near their upper ends, a suitable supportingframe for the drum and arms, and means for guiding the threads from the bobbins, substantially as described.

4. The combination of a cylindrical drum, means for rotating the drum, a series of downwardly-inclined arms arranged at diflerent heights around the drum, in near proximity thereto, which are adapted to hold a series of bobbins in contact with the periphery thereof, a suitable supporting-frame for the drum and arms, means for guiding the threads from the bobbins, tanks at the sides of the drum, and pivoted counterbalanced bent levers provided with suitable thread-guides, substantially as described.

In testimony that Iclaim the foregoing as my invention 1 have signed my name in presence of two subscribing witnesses.

ALFRED YATES.
